Hei,

What are the fundamental differences between a SNAPSHOT CONTROL FILE & CONFIGURE CONTROLFILE BACKUP …:

Can both be used for a restore? So if a snapshot is set up and running, we don’t need to take an explicit Control File Rman backup or to set CONFIGURE CONTROL FILE BACKUP…?

If each time we run an RMAN backup, RMAN automatically take a backup of the Control File (CONFIGURE CONTROL FILE BACKUP…), why do RMAN need to take a snapshot of the Control File? Isn’t it duplicating the job or it has a totally different purpose?

Thank you for your help!

Best regards,

Patrick.

It is a duplicate way to backup your control file.
But in matter of backup duplicate is a good thing.
Snapshot is easier to use but can be accidently dropped.
